Asked whether the Central Epidemic Command Center (CECC) would consider requiring all visitors to Taiwan, or alternatively visitors from areas with higher infection rates, to be tested for COVID-19 after series of imported cases reported in Taiwan.
As some public figures have suggested the mass testing, CDC Deputy Director-General Chuang Jen-hsiang said that mass testing might not be particularly beneficial.
An example, those 183 who came from Philippines, 20 had symptoms and seven tested positive, while one — case No. 471 — tested negative at the airport, but later reported symptoms and tested positive in the second test at a hospital, Chuang said.
This shows that mass testing can still miss cases, he said.
Although 163 of the 183 people had no symptoms, two of them tested positive, including one (case No. 466) who is the spouse of another confirmed case with symptoms (case No. 467), he said.
These cases would have been detected through contact tracing and within a 14-day quarantine and additional seven-day self-health management period.
